this probably should set the tty to raw input with termios.  if you're not 
familiar with the termios API, just lemme know, and i can send you a chunk of 
code to do what you need.

no one actually implements this :).  just delete it, and i'll delete the 
prototype from common.h.

once serial_init() reconfigures the tty to a more "serial" like mode, you can 
implement this properly.
